' Specizcation of Letters-Patent. 'Patented Apr., 26, 1910, Application led October 21, 1908.

Serial No. 177,845.

To all 'fwhomfit may concern: Be it known that I, BURTON D. KNICKER- Boom, citizeno the United States, residing atChicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Fountain Bath-Brushes Having Sponge Surfaces, of which the following 1s a full, clear, concise, and exact descriptlon, reference .being had to the accompanying drawing, ormmg a partof this specication.

My invention" relates to certain improvements in bath brushes or scrubbers,"andit-- has forjits object to provide an improvedl construction of brush whereby water may besuppliedcontinuously to a s on e surface of the" brush, the water supp y eingy uniform throughout.

I have shown the preferred embodiment ofvmy invention in the accompanying drawin s, which gure 1- s a longitudinal section of the side of fthe back of the brush, the sponge being'lremoved; Fig. 3 is a transverse sec? are transverse sections of the brush showingV modifications of the means fdrjsecuring the sponge in place; and, Fig. 6 isafperspective View of 'ha modification of the-securing means shown in Fig. 3. l y

Inlyftlie' preferred embodiment of my invention, Il provide a back 1, which isformed of'rubber or. other flexible material, and is provided 'with a chamber or receptacle 2..

engagement with said face thereby allowing afree iiow of water through the perforations. The sponhge 7 also preferably made of rubber 1s tted closely between rojectin sides 8 and ends 9 of the back o the brus The water 'may be continuouslysupplied in any quantity desired to the contact surface of the sponge by assingthrough the tube 3 into thechamer or receptacle\2 and thence out through the perfrations in the face of-the back 4and through the sponge to the face of the' ingthis, which occur to me, being shown in` the drawings. 'In Fig. 3 I show a chain 11 which .passes transversely through the sponge and is attached to -the inner ends of these buttons y12. y Tlue chain 11 is passed through the sponge at a point lower than the point where the buttons pass through the ears in order that the cham when attached to the buttons will hold the s onge into close relation with the .face o the back, and any tendency of the spoge to slip out of position will be prevente Forcon'necting the tube 3 with a hose I provide a connector 14 provided with a central bore for the passage of the water and having upon its periphery shoulders 15 and 16, which prevent it' from being disengaged from the tube, and a shoulder 17 to prevent 'it from being displaced from the hose with which it may be connected. `A handle 13 of any desired form and construction may be provided upon thel backl of the brush and preferably takes the form of two strips of rubber formed integral withthe brush and In I4 ig.'4 is shown one of the' other methods which I have devised for holding the sponge in position against the' back. As shown in Fig. 4, instead of having a chain assing through the sponge, I provide the buttons 18, with flattened inner portions 1 9 which engage the walls of the downwardly extending slots 20 in the sponge. Another form 4of securing means is shown 4 in Fig. 5. In this form I provide upon the under surface of the back downwardly extending lugs 21, which are arranged opposite the ears 10 and project into slots in the sponge. The buttons 23, which engage in apertures in the outer ears 10, are provided with portions which pass through parts of ing t e sponge .In place.

In Fig. 6^' is shown a rod which may lie y used in place of the chain 11 shown in Fig. 8.'

ends 9 of the back and held in position in this manner. In fact the ypart having the sponge surface may bemounted kupon the hollow back in any referred manner.

Having describe my invention what I claim as new, and desire to secure by Letters Patent, is:

1. In afbrush, the combination with a `flexible back provided with anv interior chamber or receptacle and having perfora .tions in theface thereof, of a porous body secured to'said back, and ribs on the face of the back to prevent said body from vclosing said erforations. w

2. a brush, the combination' with a flexibleback provided With an interior chani ber or receptacle and having perforations in the face thereof, of a porous body, ribs arranged on the face of said back to prevent said body from closing said perforations, 'ears depending from said back, .and means for securing said body to said ears.

3; In a brush, the combination Witha flexible back provided 'With an interior chamber and -havingl perforations in'4 the face thereof, ears depending -from said back,` a porous body disposed proximate to said back, buttons for engaging Within apertures in said ears, andm'eans for' securing said buttons A'to said porous body.

In Witness whereof, I have hereunto subscribed my name in the presence of two lwitnesses. i
